To all when it may mean: i

Be it known that I, Jonaxs Cams-torn \Vtutnur Wanna, a subiect of the King of Denmark. .dl'ling in the city of Philadelphia, Stateoi Pennsylvania. have invented certain new and useful lmprovt-zzzonts in i Surfing-Box Metal Packing. of which the following is I a full, clear, 'and exact description. reference being had to the accompanying drawings. forming ti part or this specification,

My invention has for its object the pmducfion of an plurality of pairs of semi-circular cup-like sections hereinafter described, constituting when assembled in pairs in vertical series a longittulinally and laterally aectioned sleeve around the piston rod. in combination with a pair of oppoeitely-disppsml end comprew in ring, preferably six semi-circular sections. each provided respectively with a contacting [ace coinciding with that of the adjacent interposed cup secaion:

the latter being constructed, as an essential characteristic, of composition "white metal" so-called, or of Babbitt metal, 0rd other like metal having a cornpredhle and prelerahly a resilient quality. in order that when couple-{vertically the vertiml sides of the cup section will he forced outward at or adjacent tothetopedgesapinstthepiston rod, thevertical coupe-on also bringing together the adjacent ends doachpairollelni-circnlarpacking rings orsections. u'lhaaovdfeatureaolmnatruction oi theparts elel-tallyand in their combination being as hereinafter dmihatlandpointed outin theclairns,

In tho' drawings illustrating my inmtioa, M9 1 is a vertical sectional view of the head end, partly broken away. of an engine cylinder havilg one of the usual terms ct smiling-box. conmy improved metallic packing, and with the covoringgland'in place thereon.

.' The packing. shown in Fig. l in loosely assembled position, in the stulfing-box. consists of a series or" semicylindrical cup-like sections 8, with top sections 9 and bottom sections l The sections 9 and 10 are merely top and bottom end sections presenting flat surfaces on one side with j grooved surface 12 in top section 9 and beveled surface 13 in lower section It). to adapt each to register with coinciding surfaces of the packing sections 5 whith' K are the characteristic elements. These. are conimproved form and character or metal .packing for striding-boxes of engines. and it consists of a pair or z stmcted as shown in Fig. 3 in inverted cup-like form.

the top edge 1% being beveled. and the body portion cut away at 1-5 and formed with depending side walls j 16 extending therefrom and provided at the base with tapering edges 17. the two tapered edges t'ortning between them what is substantially a groove adapted to rest on the top beveled edge"14 oi the adjacent section S lWlOW it. The interior of those sections 8 therefore form a receptacle for a graphite lubricant which will discharge through holes 18 extending from the inner wall oi the section to the interior thereof. The parts are assembled as shown in Fig. l, .and when top pressure is applied by tightening down the gland 4, the tendency will be to spread the sides 16 of the sections 8. mainly at the extreme lower ends and very little above that. hence the [rictional contact, with the piston-rod. while sutficient, will be lea than a.complete contact with the entire surface of the adjacent side wall 16 of the section.

It is preferable to drill holes It in the several sections 8(9 and 10 to more readily withdraw them-horn the stutiing bon when desired for repair, removal or otherwise. 4

Having thus described my invention I claim as new and desire to secure by Letters Patents- 1. A packing of compressible metal compo-ad of a pair of V wlncldln: semi-circular ring-like nonuniform-whoa brought Into register around a piston rod. a longitudinally sectioned sleeve. each section beta; of cap-like torla .croso-sectlon. one edge or which is herelrdand the opposite bifurcated edge has lnteriorly laellaotl walk.
